With the introduction of internet, more and more people are buying the from the online store. The glasses purchased from the online store are much cheaper. You will be able to save hundreds of dollars if you purchase the prescription eyeglasses online. The prescription eyeglasses sold at the online store have the same quality as those sold at the brick and mortar store. You can shop for the online glasses at anytime and anywhere.
Before you visit an online store to buy prescription eyeglasses, you should get a prescription from the optometrist. You don't have to mail the prescription to the online store. All you need to do is to transfer the information of the prescription through the order form. If you don't want to manually enter the information in the order form, you have to fax it to them. You have to enter the information in the right fields so that the optometrist can make the right glasses.
The prescription should contain the papillary distance. If the prescription does not include the papillary distance, you have to measure it yourself. To measure the papillary distance, you need to rest a ruler on the bridge of the nose and measure the distance between the centers of the eye pupils. You can also hire an optical expert to take the measurement. It is best that you visit an optical store to let the expert measure the papillary distance. Since you are not a skilled optometrist, you may make mistake while measuring the papillary distance. The purpose of measuring the papillary distance is to help the eyes align on the lenses so that you can see clearly.
BCVA (best corrected visual acuity) is available in some prescriptions. The BCVA value gives you a little bit information about the prescription glasses you will order. For example, a BCVA of 20/20 shows will ensure that you have 20/20 vision. If the BCVA value is not 20/20, the new prescription eyeglasses will improve your vision but it will not give you perfect vision.
After you have received your glasses, you must keep it in a clean place. The place must be dry and have cool temperature. If the temperature is too humid, it can cause damage to the lenses. To maintain your lenses, you can dub a non lint cloth with water and wipe it. It is recommended that you visit the optical doctor every year. In this way, you will be able to keep your eyes healthy all the time.
